History of Innovation

From its launch in 1997,  our patented colorizer set a new standard for efficiency and versatility.  This game-changing approach to mulch allowed a broad range of companies to capitalize on the growth and sustainability of the premium mulch market. We have continued to raise the bar by developing remote monitoring systems and other tools that help mulch producers maximize productivity and minimize costs.

How it Works

Our patented technology injects water and colorant directly into the grinding chamber, using the force of the grinding process to thoroughly mix colorant into the wood fiber. The whole process is completely self-regulated and easy to adjust to match wood fiber consistency and mulch specifications. The colorant injection turns on automatically when raw material enters the grinding chamber and turns off when the grinding chamber runs empty, minimizing colorant usage and mess.

Advantages

Our exclusive grind & color system maximizes mulch quality while minimizing costs. By reducing the number of machines and steps required to produce colored mulch, Rotochopper equipment dramatically lowers handling costs and spillage. Known for precision grinding capacity, Rotochopper grinders minimize the percentage of fines, increasing mulch volumes while decreasing colorant usage.
